DisplayPort is a digital video and audio transmission standard that supports high resolution glossy, high refresh rate and high color depth displays.

DisplayPort source can transmit video and audio signals to the receiver over a single cable.

HDMI is a digital audio video interface commonly used to connect TVs, monitors and other multimedia devices.

The HDMI interface can simultaneously transmit video and audio signals that support high-definition video and multi-channel audio.

Although both DisplayPort and HDMI are digital interfaces, there are differences in physical connections and signal transmission.

The HDMI signal can be converted into an HDMI signal via an adapter or converter for connection to HDMI devices.

However, the HDMI signal cannot be directly converted to a DisplayPort signal because the HDMI interface does not provide some of the functions and protocols required by the DisplayPort.

Therefore, DP HDMI adapters or converters can only provide unidirectional transmission from the DisplayPort source to the HDMI receiver.
